Similar letters. refer to similar i.parts throughout the severalviews. j 'F or the purpose of tying a bag, .it is necessary to grasp and gather tightly together the bag at its neck and hold it while a suitable wire,string or other tieisplaced around the neck and secured in position. i In order to accomplish this result, satisfactorily,'it is necessary; to provide simple andsubstantial mechanism, which will operate automatically and continuously. It is'also desirable that tlie mechanism shall be operative when the bag to. be tied is constructed of paper,

as well asiofcloth, canvas or other fabric. 'In order that the'machine may *be adapted p for .tying bags of cement or other heavy substances, it is advisable "tohave it arranged so thatthe bag will not be'necessarily i lifted or moved" duringthe operation of 3 tying. And When the mechanism is used for tying bags of cement or other finely powdered substances, the working parts of the mechanism should be so protected and constructed that they will not become clogged by the substance operated upon.

I have provided bag tying machine which complies with the requirements above noted and therebyovercomes-the difficulties heretofore experienced in tying bags; and have produced a snnple, inexpensive and easily operated machine, which will tie bags of paper, as well as of cloth, canvas or other fabric, and so constructed and mounted that there islittle or no dangerofinterruption because of disarrangement of parts or inace place where the bag is to be operated upon.

Referring to the drawing, upon a suitable base, A, see Fig.2, 1 mount thesupporting frames, B and ,0, each of which frames is providedwlth the bear ngs, b, o. l/Vithin the bearings, 'Z). Z), reciprocates the supportingarni, D, and in like manner within the bear ngs, c,jc,qreciprocates thejaw sup? porting arm, These arms, D and 100 are arranged in line, are preferably. square in cross 'sect1on,and are provided onltheir lower sides with racks. the, respectively.

To the end'ofthe' arm, D ,'I secure a forked .bllOCl ,"F .l1a/V1ng gtwo outwardly" flaring The block, F, is secured to the arm, D, by

prongs, forming one V-shaped gathering jaw F, that is adapted to engage the bag.

means of suitable bolts, f, or in any suitable manner. a

The arm, E, has secured to its end a block,

G, which is forked having two outwardly slightly separated prongs on each side, flaring outwardly, forming the V-shaped gathering jaw, G, capable of permitting the.

prongs forming the jaw, F, to enter between the double pair of parallel prongs forming the jaw, G, when the supporting vso arms are shifted ,inwardly toward "each other. When this occurs,the prongs of the V-shaped jaws overlap, inclose the upper portion of the bag, and tightly gather the same into a 'neck about which the tie is placed.

The block, G, is secured by suitable bolts; g, or in any suitable manner, to the end of the arm, E.

For the purpose of actuating the arms, D 'andE, and likewise the jaws, F and G, I

arrange the pinions, H and J, engaging, respectively, with the racks, cl and e, the pinions being mounted upon shafts, H and J, respectively. The shafts H and J are provided respectively with pinionsh'and j,

with which toothed segments H J respectively engage. Said segments being connected by the rods, L and L, respecand pinion in motion.

means for accomphshmg this result may be tively, to disk crank, M, whichis fixed upon the shaft 30 Which is in line with a .shaft 26 to whichis fixed the power'pulley, N. The disk crank M comprises a set of. three disks connected by a pair of crank pins. with which the inner ends of the connecting rods L engage, as clearly shown in Figs. 1 and 2.v

I cause the jaws to work by the operation of a clutch mounted, in connection withthc shafts 26 and 30 carrying the power pulley,-

N, .and the disk crank, M, respectively, which will be hereinafter more particularly described. Indeed I do not want to limit myself to the manner of connecting the arms, D and E, with rack and pinion, or the meansdescribed for setting the said rack Other convenient used, since allthat is necessary is to relatively shift the arms carrying thejaws, so as to cause them to approach each other, intermesh and separate alternately.

For the purpose of tying a bag after it has been grasped by the jaws at the neck and held tightly together, I have provided a; wire tie-piece, 0, Fig. 14, having at one end a loop, 0, which I place through an opening, D, Fig. 4 indie arm, D, where it will occupy a position in a, groove, D in said arm in the line of movement of the plunger, P, see Fig. 9. The plunger, P, be-

ing secured near one end to the reciprocat- Fig. 4.

slotted as at 19.

ing bar, P, carrying the rack, P The reciprocating bar, P, is preferably provided with atongue (see Fig. 9) that fits within the dovetailed groove, p, in arm, D, see

In order to provide for theproper arrangement ofthis groove carrying thectiepiece and the engagement of the tie-piece with the bag, I place at the junction of the prongs forming the jaw piece, F, a block,

s, formed of two pieces shownin Figs. 10

and 12 within one piece of which there is anopening or chamber S as shown in Fig. 10. The other part of the block, S, also contains a groove, D around the semi-circular opening which forms the side of the block toward the engaging jaw, G, Fig. 7. The groove D extends through the abutting edges of the sections of block S and opens into the chamber S and into the groove D .The jaw, G, has, a block, T, at the junction of the jaw, which contains a groove, D on the inner semi-circular face, see Fig. 11, which forms a continuation of the groove, D and D when the jaws are brought together. It should be noted that the groove D is diamond shaped in cross section, as seen in Fig. 4 and is tangential to the grooves D and D The inner working faces of the V-shaped jaws F andG thatact on the material of the bag to gather it into a neck are inclined to the direction of movement of the jaws, preferably at an angle of about forty-five degrees, and the faces of the prongs of each jaw are preferably at an angle of ninety degrees to each other. The blocks S and T i are arranged at the junctures of the prongs of the jaws, and abut in closed position to constitute a closed neck-forming and tieshaping die, as shown in Fig; 18, that snugly embraces the neck of the bag, and is arranged to shape or guide the wire tiepiece 0 about the neck of the bag at the point where the material is most tightly held.

When the jaws are closed, and the block sections S and T are brought into engagement, the plunger P is moved inward and pushes the tie-piece 0 into the continuous circular grooves D and D in the faces of the abutting blocks. As the tie-piece is forced forward, it will pass through the groove, D into the groove, D*, and because of the substantially circular contour of the passage-way, which forms the groove, D will be bent and caused to traverse a sub stantially circular path, and entering the groove, D continuing its circular course the end of the tie will enter the chamber, S, but just as it is about to pass into the chamber, S, the loop, 0, on the end of the tie-piece is emerging from the groove, D and the forward end of the tie-piece 'will pass through said loop, as shown in Fig. 15- As the Plunger still continues to force the tiepiece forward the end of the loop will engage the tie-piece near its forward endand cause a bend to take place therein, because the end of the tie-piece has entered and engaged with the wall of said chamber, its passage forward being prevented, and thus will be bent over upon itself, as is indicated in Fig. 16, the entirecomplete movement, however, of the plunger jnotbeing shown in said figure, and therefore the final position of the end of the tie-piece is not illustrated therein. Upon the complete movement of the plunger, the end of the tie-piece is bent well back uponitself, the parts thereof entering the notch pof the plunger P. The recess D is diamond shaped in cross section, so that thetie-piece is held therein with its eye 0 vertical to insure the proper threading of the opposite end of said tie-piece therethrough'.

For the purpose of communicating motion to the plunger I arrange a gear wheel, Q, preferably mounted as shown in Figs. 20 and 21 on an arm, 9, pivoted to the arm, D, permitting, therefore, of a longitudinal movement of the gear wheel. The gear wheel, Q, is adapted to engage with the rack, P and as the arm, D, is moved, as indicated by the arrow in Fig. 20, the pinion, Q, engaging with the gear wheel, Q, will move the arm, 9 to the position shown in Fig. 21, when the gear wheel is brought into engagement with rack, I, which isthen forced backward in the direction indicated by the arrow. The pinions Q and Rare operated in opposite directions, so that when the gear wheel, Q, engages the pinion R the plunger is projected forward toward the jaws, the jaws being closed. When the jaws begin to open the gear wheel, Q, breaks connection with the pinion, R, and soon makes connection with the pinion, Q, which moving in a direction opposite to that of the pinion, It, will. set the gear wheel, Q, in reverse motion, tending to withdraw the plunger. I have shown the pinions, Q and R,

mounted upon vertical shafts, respectively,

connected by the cross belt, U. The end of one of the shafts, r, carrying the power pulley, which is connected bV the belt, V, to a pulley, V, fixed on the drive shaft 26 as shown in Figs. 1 and 3. I do not wish,

however, to limit myself to this means of that it tends to prevent the gear wheel from spinning after separating from" the pinions Q and R, thus facilitatingthe ready meshing with the rack,'l at the point of engagement. I have also constructed the gear wheel, Q, in themanner illustrated'in Fig.

23, so as to provide for the impact occasioned by its engagement with. the pinions,

Q and R. Thus I have placed a bushing of resilient material, preferably rubber, W, within the hub of the wheel, separating that portion carrying the teeth'from the brass thimble, W, engaging the shaft. Of course I do not limit myself to the use of the pinionconstructed in this manner, as

any pinion might be used in its place, but I prefer my improved pinion for the reasons specified.

As I have stated the gear wheel, Q, is

mounted upon the pivot-ed arm, 1, allowing for a slight longitudinal movement of the pinion. This is for the purpose of enabling the gear wheel, to engage therack, P when it contacts with the pinions Qnand R. Then the arm D'iismoved forwardit carries with it the gear wheel Q 'until'the latter engages the pinion R. *The wheel Q; and arm q are then swung backwardly, andthe wheel engages the rack P The jaws are then closed, and the pinion R and gear wheel Q act to force the rack P and plunger P farther in a forward direction and described. movement of the plunger, the rack P will move out of engagement with the gear wheel It. Vhen the arm D moves back, the gear wheel Q, rack P and plungerPcmov'e back with it until the gear wheelcontacts with the pinion Q, when it is then swung with the arm" (1, and rotated to further withdraw the rack P andplunger connected to the rack.

I have referred to a clutch adapted to'be placed upon the drive shaft, and I now proceed to explainits construction and operation.

It will be apparent that the movement of the jaws forward and back provides for the closing of the sack and bag, and the separa tion of the folding devicetherefrom would require acomplete revolution of thedisk 110 place the tie about the neck of the bag, as

At the end of the forward crank, M. But the power shaft 26 is running continuously and it is, therefore, advisable to arrange a clutch device, whereby the movement of the jaws may be controlled. To do this I have shown in Figs. 18 and 19 one form in which the disk, 25, fixed to the power shaft, 26, carries a projecting catch, 27, upon one side adapted to engage the end of the dog, 28, pivoted securely to a disk, 29, and which disk, 29, is keyed to a shaft, 30, that carries the crank disk, M. It will be seen that with the revolution of the disk, 25, when the projection, 27, thereon, is in engagement with the dog, 28, the disk crank, M, will be rotated.

For the purpose of breaking connection between the dog, 28, and the catch, 27, I provide a finger, 31, capable of being forced into the path of the movement of the dog, 28, and to break connection between the dog, 28, and the catch, 27. This will permit the rotation of the disk, 27 without movement of the disk, 29, and therefore prevent the rotation of the crank disk, M. It is, of course, necessary in order to allow the finger, 31, to press the dog, 28, out of engagement with the catch, 27, that there should be room within the disk to permit the dog to be thus moved, and I have shown in Fig. 19 a recess, .32, within which the dog may enter.

For the purpose of forcing the dog out of.

the recess, 32, and placing it within the path of the movement of the catch, 27, I have a spring, 33, suitably seated and connected. The pulleys N and V, and the clutch member 25 rotate continuously with the power shaft 26. The clutch member 29 and. crank disk M of the shaft 30 are normally stationary with the clutch dog 28 held in the recess 32 by the finger 31. When the finger is withdrawn the dog 28 is forced outwardly by the spring 33 into engagement with the shoulder 27 and the clutch member 25. Shaft 30 and the part carried thereby are then rotated to a single revolution or until the dog 28 is again engaged by the finger 31 and moved thereby inwardly into the recess 32. To move the finger, 31, I may arrange a suitable pedal or other device, not shown, which will readily suggest itself to any mechanic. v

I have described the disk crank, M, being connected by the rod, L, L, with the segments, H J I show in Fig. 17 a crank arm, 34 which is a well known equivalent for the crank disk, M, and which may be substituted for the crank disk, M, if desired. It being understood that I do not wish to confine myself to the particular means de scribed or illustrated for communicating motion to the parts of the mechanism.

On each of the prongs forming the jaw, G, near the block, T, I preferably place a projecting lug guard, K, for the purpose of preventing the bag from crowding into the groove D of the block T and thus obstructing the passage of-the tie-piece, O. 1

The guard lugs K prevent the material of the bag from being caught between the abutting die-forming blocks S and T, which would prevent the proper passage of the tie-piece through the grooves D and D and around the .neck of the bag.
